Flush toilet provided with means to enhance water efficiency thereof and to avert obstruction of drainpipe thereof

Abstract

A flush toilet comprises a bowl, a water tank, a drainpipe in communication with the basin of the bowl and a septic tank, and a loop connected between the bowl and the drainpipe to enable parts of water and air in the drainpipe to flow into the bowl basin at such time when the toilet is flushed, thereby enabling the waste matter to fall rapidly by its own weight into the septic tank.

What is claimed is:  
     
         1 . A flush toilet comprising: 
 a bowl having a basin;    a water tank in communication with said basin of said bowl;    a drainpipe in communication with said basin of said bowl and a septic tank; and    a loop in communication with said drainpipe and said basin of said bowl.    
     
     
         2 . The flush toilet as defined in  claim 1 , wherein said loop is provided with a shut-off valve.
